scent of 7000 feet for the distance of 1G0 miles down to the junction of the 
Dihang river with the Brahmaputra ; this does not give an excessive slope 
compared with other Himalayan rivers. 
One of the most interesting results of the present exploration is, that 
it affords an explanation of the probable source from which the Subansiri 
river draws its large volume of water. The fact of its volume being so 
large, coupled with the erroneous information derived from Nain Sing as 
to the supposed south-easterly course of the Sanpo below Chetang, had 
given rise to a conjecture that the Subansiri was the recipient of the Sanpo. 
That this conjecture is also erroneous, has been shown by Lieut. Harman’s 
recent operations for measuring the discharges of the principal affluents of 
the Brahmaputra river, which are briefly described at pages 16 and 17 of 
the General Report of the Operations of the Survey of India for 1877-78, 
and more fully in the Journal of the Asiatic Society of Bengal, Yol. 
XLVIII, Part II, No. 1, 1879. These operations indicate that the volume 
of the Dihang is from twice to three times as great as that of the Subansiri, 
so that of the two the Dihang has a far better claim to be the recipient 
stream. Still the difficulty remained of accounting for the large discharge 
of the Subansiri from so small a drainage area, and this difficulty is now 
removed, by the discovery of a large area below the great bend in the Sanpo 
around what may well be one of the two principal basins of the Subansiri 
and its affluents.

4. Notes on the Gold Coins found in the Akin Posh Tope.—By Major- 
General A. Cunningham, e. e., c. s. i. 
(With plates IX, X, XI.) 
When Dr. Iloernle wrote his notice of the gold coins found in the 
Ahin-posh Stupa at Jalalabad, he was not aware that the inscription on the 
coins of Wema Kadphises had been discussed so long ago as 1863 by Pro¬ 
fessor Dowson and myself, quite independently of each other.* Had he 
read our papers, he would have seen that several of his emendations of
